Embodiment one
As shown in figure 3, present embodiments providing a kind of star orbital prediction technique, it is applied to mobile terminal, may include:
Step 301, the geographical location information of current geographic position is acquired；
Step 302, the starry sky picture under current geographic position is shot；
Step 303, according to the starry sky picture and the geographical location information, the star orbital figure of current geographic position is generated
Picture.
In the present embodiment, pass through mobile terminal gathering geographic position information and shoot starry sky picture, recycles geographical location
Information and starry sky picture generate the star orbital image of current geographic position, and current shooting condition can be predicted by mobile terminal
Star orbital image under (including acquisition parameters, shooting location etc.), convenient for user to the star orbital picture formed under the conditions of current shooting
It is prejudged, on the one hand can be used as the reference of star orbital picture pattern, be on the other hand alternatively arranged as user and adjust shooting condition (as clapped
Take the photograph place, acquisition parameters etc.) supplementary means, find suitable shooting location and acquisition parameters, convenient for user to take ideal
Star orbital picture.
In some implementations, the process that the star orbital image of current geographic position is generated in step 303 can be by such as
Under type is realized: the visible fixed star of current geographic position and its distributing position are identified from the starry sky picture；According to describedly
Location information is managed, determines angle of the star orbital central axis relative to current geographic position；According to star orbital central axis relative to working as
The visible fixed star of the angle in preceding geographical location, current geographic position and its distributing position form the star orbital figure of current geographic position
Picture.
In practical application, fixed star and its distribution position can be identified from the starry sky picture by image analysis algorithm
It sets.For example, can identify fixed star from the starry sky picture by object recognition algorithm, and then obtained again by image procossing
The distributing position of each fixed star.Wherein, object recognition algorithm specifically can be using the object recognition algorithm suitable for image procossing.
Wherein, in step 301 it is described acquisition current geographic position geographical location information, may include: to pass through the whole world
The latitude and longitude information of position system GPS acquisition current geographic position；Angle information is looked up by gyroscope acquisition current shooting.
In this way, during the star orbital image of above-mentioned generation current geographic position, it can be according to the latitude and longitude information and upward view angle
Degree information determines angle of the star orbital central axis relative to current geographic position.
In practical application, angle can be looked up with what is shot according to the longitude and latitude of current geographic position, determine arctic astrology
For the angle of current geographic position, Polaris is the center of each fixed star motion track relative to the angle of current geographic position
Angle of the axis relative to current geographic position.
In practical movement, when it is zero that Polaris is relative to the angle of current geographic position, that is, when face Polaris
Star orbital image is concentric circles, the corresponding circle of a fixed star, the center of circle of concentric circles where Polaris on axis, radius with it is each
Distance dependent of the fixed star with respect to the earth.Shooting location is different, that is to say, that current geographic position is different, then the star orbital taken
Image may be a part of the concentric circles.In practical application, the process for forming star orbital image may include: first determining current position
Present star and its distributing position are formed by together when managing the visible fixed star in position and its distributing position, then determining face Polaris
Heart circle, finally the angle further according to the central axis of each fixed star motion track relative to current geographic position intercepts the concentric circles
In a part, the star orbital image of current geographic position can be obtained.This form mode is merely illustrative, can also in practical application
To be preset in the CPU of mobile terminal by being write celestial operating rule and its relevant calculation formula as computer program, by
CPU directly according to the visible fixed star of current geographic position and its distributing position, current geographic position longitude and latitude and look up angle
The star orbital radius is calculated, then draws out the star orbital image.In this regard, herein with no restriction.
In some implementations, to be checked convenient for user, can generate current geographic position star orbital image after,
